Lockscreen is displayed between activities

Question

I work on a kiosk app which can launch other android apps. It runs on top of the lockscreen. The issue I am seeing is that the lockscreen is displayed briefly between activities

Answer 1

How can I launch the other activity without it briefly showing the lockscreen first?

An easier way of achieving this would be to have a dummy (plain-view) activity running before you launch activity-1. This way, when you do finish activity-1, dummy-activity will take over, followed by activity-2 coming into the foreground.

You will (most likely) also need to tell the system not to provide window animations. Do so by adding this to your application theme:

<item name="android:windowAnimationStyle">@null</item>
